The discovery of the first-ever asteroid to arrive from interstellar space is full of lessons for us all. On October 19th, astronomers discovered an objectunlike any other we’d seen before: a […]
There are plenty of questions we don’t know the answer to. With quantum gravity, they might be solved! This article is written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized […]
For the first time, I genuinely enjoyed the new series. There’s been one question that’s bothered me in every episode since Star Trek: Discovery began: why would anyone want to be […]
With a journey of 130 million light years, both signals should move at the speed of light. So why did one get here first? On August 17, after a journey taking […]
If you think we know it all, you’ll never be ready for the next big breakthrough. When you’re taught the scientific method, you think of a neat procedure you can […]
If a former Nazi realized its importance nearly 50 years ago, perhaps we all can, too. Around the country and around the world, there is no shortage of human suffering. Poverty, […]
Don’t believe in dark matter or dark energy? Your view of the Universe just got a lot more difficult. If you ask an astrophysicist what’s the greatest puzzle in the […]
There’s no science in this episode of science fiction… but there’s a lot of suspicious happenings that no one’s noticing. Following up on the best episode of the season, thus […]
Do we need quantum gravity? We sure do… and here’s how we’re trying to get there! Our current best theories describing the Universe, general relativity for gravity, quantum field theory for […]
Very sure. Here’s how we know. You’ve no doubt heard that the Universe itself has been around for 13.8 billion years since the Big Bang, and that scientists are extremely confident […]
Each discovery we make seems to raise even more questions. It’s a wonderful example of how science never ends. On August 17th, both the light and the gravitational wave signals from […]
All sorts of futuristic technologies have come true. So why are astronauts all still weightless? Put a human being up in space, away from the gravitational bonds of the surface […]
Okay, so everyone who wanted to order an autographed copy (or N autographed copies) of my new book, Treknology: The Science of Star Trek from Tricorders to Warp Drive, here’s […]
And if we don’t prepare to catch it now, it’ll be too late. Since 1990, the Hubble Space Telescope has been redefining how we view our Universe. From hundreds of miles […]
The first detections were incredible. But now the real fun — and the real science — truly begins. On August 17, the signals from two merging neutron stars reached Earth after a journey of 130 […]
For the first time, we’ve seen neutron stars merge. At last, the gravitational and electromagnetic sky are one. “It’s becoming clear that in a sense the cosmos provides the only laboratory […]
At long last, we’re getting a confrontation with ethics, with science, and with human frailty, not just the Federation at war. “You are… six years old. You are weak and helpless! […]
Either possibility offers a tremendous existence, but philosophically, there’s so much more to think about. “If the doors of perception were cleansed every thing would appear to man as it is, […]
